How to search Gmail mails that have only one conversation [duplicate]

Question

Is there any way I can find all the emails that I sent but have not been replied to by anyone? (One email conversation.)

Answer 1

It looks impossible with the standard search bar.

I tried searching for conversations that do not contain "Re:" or "Fwd:", but there is something broken about GMail search when it comes to that!

• If I use search string subject:"fwd:", I get conversations with forwards.
• If I use search string -subject:"fwd:", I get all e-mail (not just conversations without forwards!)
• If I use search string subject:"re:", I get conversations with replies.
• If I use search string -subject:"re:", I get all e-mail (not just conversations without replies!)

So obviously searching for -subject:"fwd:" -subject:"re:", which really should work, fails.

-(subject:"re:" OR subject:"fwd:") does not work either.

-{subject:"re:" OR subject:"fwd:"} does not work either.

So obviously combining that search with from:your e-mail address would not work either.

A kludge would be:

1. Make a new label (e.g.NRF, for "No Replies or Forwards", or "gmail's search is NeRFed").
2. Make a new filter that applies the new label to to all e-mails from yourself (make it retroactive).
3. Search for subject:"fwd:", and remove the new label from all of the results.
4. Search for subject:"re:", and remove the new label from all of the results.
5. (Do the same for subject:"fw:" since some e-mail applications use that.)
6. Search for the new label (e.g. label:NRF).

That should give you what you want.
